Guys, here's a stupid idea! I've got most of the bits to make a Morgan Jones
headphone valve amp apart from the mains transformer and choke...so after a
couple of glasses of wine I got thinking. The current consumption isn't
going to be too great (how do you work out the current consumption of a
valve?)...what about 24 PP3 9v batteries in series to give me a clean 216V
DC HT. And a wall wart to run the heaters?
